[英]Angular2: Unable to load components
我正在练习angular2,并且尝试使用属性指令,但是无法加载组件,也不知道我做错了什么
朋克: http ://plnkr.co/edit/o3llvK?p=preview
应用程式:
//our root app component
import {Component} from 'angular2/core'
import {AttributeDirective} from './attributedirective.component'
@Component({
selector: 'my-app',
providers: [],
template: `
<div>
<h2>Hello {{name}}</h2>
<my-attr-directive></my-attr-directive>
</div>
`,
directive: [AttributeDirective]
})
export class App {
constructor() {
this.name = 'Angular2'
}
}
attributedirective.component.ts:
import {Component} from 'angular2/core'
import {HighlightDirective} from './highlight.directive'
@Component({
selector: 'my-attr-directive',
template: `
<div myHighlight>Highlight me</div>
`,
directive: [HighlightDirective]
})
export class AttributeDirective{
console.log("test");
}
Highlight.directive.ts:
import {Directive, ElementRef, OnInit} from 'angular2/core'
@Directive({
selector: '[myHighlight]'
})
export class HighlightDirective implements OnInit{
private _defaultGreen = 'green';
constructor (private _elRef: ElementRef){}
ngOnInit():any{
this._elRef.nativeElement.style.backgroundColor = this._defaultGreen;
}
}
有人可以帮我解决这个问题吗?
这将修复您的unk ...
export class AttributeDirective{
consturctor(){
console.log("test"); // you can't use console.log directly as you are working with typescript not javascript....
}
}
